Peter Barnes shows us how to build a new economic sector that is held in trust for future generations. Ecosystems and their services would be managed for long-term benefit rather than short-term profit, and all Americans would get cash dividends.

Barnes shows how capitalism—like a computer—is run by an operating system. Our current operating system gives too much power to profit-maximizing corporations that devour our commons and distribute most of their profit to a sliver of the population. And government—which in theory should defend our commons—is all too often a tool of those very corporations.

Barnes proposes a revised operating system—Capitalism 3.0—that protects the commons while preserving the many strengths of capitalism as we know it. His major innovation is the commons trust—a market-based entity with the power to limit use of scarce commons, charge rent, and pay dividends to everyone.

Capitalism 3.0 offers a practical alternative to our current flawed economic system. It points the way to a future in which we can retain capitalism's virtues while mitigating its vices.
